SYS390B satellite timing remote nuclear current meter
Introduction: SYS390B wireless high-voltage satellite timing remote nuclear phase current meter, also known as wireless high-voltage satellite timing remote nuclear phase device, consists of X receiver, Y receiver, X detector, Y detector, telescopic insulating rod, etc., and has wireless high-voltage satellite timing Remote nuclear phase meter, wireless high voltage clamp ammeter, wireless high voltage phase meter, wireless high voltage phase sequence meter, wireless high voltage electroscope function. The receiver adopts a 3.5-inch true color LCD screen, and displays the real-time phase angle, current, frequency on the same screen, and the voice broadcasts "X signal normal, Y signal normal, in phase, out of phase" and other information. Both receivers have built-in 6-in-1 multi-mode satellite timing module to support multiple satellite navigation systems, including China's BDS (Beidou Satellite Navigation System), US GPS, Russia's GLONASS, EU's GALILEO, Japan's QZSS and satellite enhancements. The system SBAS (WAAS, EGNOS, GAGAN, MSAS), which contains 32 tracking channels, can simultaneously receive GNSS signals of six satellite timing systems, and realizes joint timing to ensure satellite timing and phase accuracy. The satellite timing nuclear phase can realize ultra-long-range nuclear phase. The nuclear phase distance is more than 500km. It can also be in the basement and mine under the nuclear phase, and the timing accuracy is less than 30nS. The nuclear phase meter can fully intelligent nuclear phase for voltage lines from 100V to 550kV, and is compatible with the functions of ordinary nuclear phase meters. The distance between the common nuclear phase of the open ground can reach 160m. It can also be used for high-voltage lines and fully sealed ring network cabinets with low-voltage induction point nuclear phase. The bare wire detectors of 35kV and below can directly contact the nuclear phase, and the bare wires above 35kV use non-contact nuclear phase. The non-contact nuclear phase is The detector is gradually approached to the conductor to be tested, and the nuclear phase can be completed when the electric field signal is sensed, so that it is safer to directly contact the high-voltage conductor! The detector's innovative integrated hook design, in which the X detector has a built-in double-layer flexible coil, Rogowski Coil, is a toroidal coil that is evenly wound on a non-ferromagnetic material, with no hysteresis effect, almost Zero phase error, no magnetic saturation, and extremely high linearity. The flexible coil is the current-to-time differential. The integrator integrates the output voltage signal to truly restore the measured current and output the complete signal waveform. The instrument can test the high-voltage current 0~20000A, and can measure 168mm wire or 168mm×245mm. Busbar. The X detector can also be used for electric leakage inspection: hook the X detector on the cable and patrol along the line. If the receiver changes from a large current display to a small current or no current display, the point is the cable leakage point.
